SHEET-DELIVERY APPARATUS.

SPECIFICATION forming part of Letters Patent No. 698,914, dated Apr129, 1902.

Application filed April 19, 1901.

t'o from a printing-press can be reversed or delivered on the receiving-board with the face or printed side down, if desired.

The invention resides in certain novel details of construction set forth in the following i' 5 specification and claims andillustrated in the vannexed drawings, in .which- Figure 1 is a plan view of a delivery apparatus. Fig. 2 is a side elevation of Fig. l. Fig. 3 is a section along Fig. 4, showing o a side elevation of tape and pressure rollers.

Fig. 4 is a section along y y, Fig. 3. shows a modification.

A printing-press frame is indicated at A and impression-cylinder at B. The carriage Fig. 5

G has tapes O running about rollers H H H2 H3. The manner of operation of the tapes and reciprocation of the carriage are set forth in United States Patent No. 335,066, of January 26, 1888, andNo. 506,990, of Octo- 3o ber 17, 1893, and need not be detailed here.

Pressure-rollers are shown at b acting on the tape or onto the tape-roller H; and a reverser or curler is shown at c. A sheet fed oif the tapes and passing between rollers H and l) 3 5 will be reversed by the fingers or curler cthat is, bent so as to fall on the receivingboard printed face down. The roller H has a ratchet-and-pawl connection with gear q, running on rack e, so that as the carriage 4o moves forward the gear rotating or running along the rack will rotate the roller H to move the stretch of tape between roller H to H2, while on the return of the carriage the ratchetand-pawl connection remains idle or slips,'so

as to leave roller H stationary or nnaifected by the rotation of gear q. In the forward travel of the carriage the top stretch of tape not only moves with the carriage, but has furthermotion by reason of the roller I-I being o rotated by the ratchet-and-pawl connection with gear q and rack e. The sheet is thus Serial No. 56,630. (No model.)

fed from the tape under the presser-roller b and curler c with increased speed.

The presser roller or disks b can be mounted in a movable support or lever-frame, such as arms f and rock-shaft g, and a cam or wedge t' can be arranged o r fixed to lift the arm h, Fig. l-that is, the presser-roller b-o the tape or out of action to run onto a sheet or so that the leading edge of a sheet coming from a printing-press can come under the presser-roller and be grasped between the latter and the tape when on the forward stroke of the carriage the presser-roller contacts with or drops onto the tape.

The lifting arrangement or wedgeihas been found practical; butit has been found that the device will also work when the presser-roller h is loosely mounted-sayin a slot-bearing, as shown in Fig. 5. It has also been found practical to make the face of the presser-roller elastic or yielding-say of rubber.

The curlers c can be secured to or form part of a bracket carried by or connected to the 'taper-carriage, and this bracket can also supportthe bearing of the presser-rollers. By removing this bracket or the reverser c the sheets will be left free to deliver printed face up. Sheets can thus be reversed or not, as called for.

In placeof curlers c the roller b could be made to act on tape-roller H forward or so far to one side of the top line or uppermost point of such tape-roller whereby the leading edge of the sheet is bentdown as it is leaving the tape-roller to reverse or curve about said roller and to cause the sheet leaving the carriage in its forward travel to fall on its face or printed-side. f

A brake or friction has been found serviceable whenrunning at high speed and there is nothing to check the delivery-rollers or "the momentum of the tape-rollers is retarded IOO resistance can be applied. The brake clasping a roller-say, for example, the shaft `of tape-roller l-la-can be made to check excessive speed.

What I claimlas new, and desire to secure by Letters Patent, is-

l. A delivery apparatus for printing-inachines comprising` a reciprocating tape-carriage and tape-rollers, and a presser-roller made to act on a tape-roller to one side of the top line so as to cause a sheet leaving the tape-rollers to reverse or curve about said.

roller substantially as described.

2. A delivery apparatus for printing-ma? chines comprising a reciprocating tape-car- 4 riage and tape-rollers, a presser-roller made y to act on the tape, a reverser, and a brake or friction appliance made to engage one of the rollers for checking the movement of the tape substantially as described.

3. A delivery apparatus comprising a reciprocating tape-carriage and tape-rollers, a pressure-roller made movable toward and Lfrom the tape, a reverser or curler, and a sup- GEORGE P. FENNER..
